Cree is widely regarded as a reputable LED manufacturer. Warm, white light is generally more comfortable. It's also less harsh on the eyes than cool, white light. If you need long-range light, get a flashlight with a smooth reflector. It will have more throw distance. Mechanical switches often offer tactile feedback. Users can feel a distinct click or resistance when they press the switch. The rear switch of the HA23 is rugged and durable. It can withstand harsh conditions and repeated use.
